Yes, I've read and read and read every single FAQ and info page from Presonus and lots of threads here in this forum.
I still wanted, before I shop for a new interface, to at least get confirmation once and for all from others that once you upgrade to any MacOS after Yosemite 10.10, that because the VSL monitoring software no longer functions, being able to use Low Latency Monitoring when working specifically in Pro Tools is absolutely not possible anymore.
I have that totally correct, right?

I was reading about how you can use the Audio/MIDI setup to get a cue mix out of outputs 7/8 and I did tons and tons of testing, but that method absolutely does not work at all.

I'm on MacOS Sierra 10.12.6, my 1818vsl is on the most up-to-date firmware it can be, and I believe I'm dead in the water specifically when it comes to Low Latency monitoring.
Otherwise, this 1818vsl has been totally fantastic. And thankfully I can run at a fairly low buffer.

But I still wish I could truly use Low Latency Monitoring with my config.
I just believe from all I've gathered that I cannot.

Can you guys please confirm that for me 100%?
Thanks!
